Dixon: NEW AND RARE AFRICAN MOSSES is 
T. gastrodes however is more marked as a species than some, 
in the widely spreading leaves, almost at right angles to the stem 
when moist, very widely cordate-oval, abruptly narrowed to a 
short but rather fine acumen; the cells are moderately papillose, 
the alar very numerous, extending half-way up the leaf at the 
margins. It is probably only known hitherto from the original 
station in Angola.
